Finding EDWARD KEITH THOMAS b. 1924

I am trying to trace my father EDWARD KEITH THOMAS born in 1924 (Reading, Berkshire) who was in the UK Royal Navy during WW2. He absented himself from HMS Golden Hind in Sydney Australia around September 1946. He married my mother in July 1943 in Reading, Berkshire. I was born in 1944. I am not aware that he returned to this country but his mother and maybe other family may have still been here although I haven't been able to trace her. He may well be deceased now but could have married over in Australia and had more children. My mother was divorced from him in December 1951.
